CORN-HUSKING MACHINE SPECIFICATION forming part of Letters Patent No.774,863, dated November 15, 1904. Application filed February 18, 1904.Serial No. 194,293. (No model.)

To all whom it may concern.-

Be it known that we, CULLEN BORDEN, residing at Hume, in the county ofEdgar and State of Illinois, and JAMES SANFORD BORDEN, residing atLouisville, county of Jefferson, and State of Kentucky, citizens of theUnited States, have invented a new and useful Corn- Husking Machine, ofwhich the following is a specification.

7 Our invention relates to corn-husking machines that are operated inthe field and husk the corn from the standing stalks without cuttingthem off; and the objects of our improvement are simplicity ofconstruction, ease of operation, comparative inexpensiveness ofmanufacture, rapidity of operation, efiectiveness, and adaptability tovarious conditions of the crop to be operated on.

In the accompanying drawings and the following specification will beshown the man ner in which we attain these objects so clearly that anyone skilled in the art to which our invention pertains will be able tounderstand, make, and operate it.

In the drawings, Figure 1 is a Fig. 2, a rear elevation with the polesand steering-wheel cut 01f; Fig. 3,'a rear elevation of thesteering-wheel, seat, and adjacent parts; Fig. 4, a side elevation withportions cut awayto show working parts, and Fig. 5 a detailed view ofthe husking-rollers.

Similar reference-numerals refer to similar a parts throughout theseveral views of the drawings.

The body of the machine consists of the yoke-shaped frame 1 and the arch41 at the rear of the frame.

2 and 3 are husking-rollers journaled forwardly in frame 1 and at therear in arch 41.

5 is the drive-wheel, which is rigidly attached to its axle, and 6 isthe wheel on the opposite side of the machine, which is loose on itsaxle. j

At the sides of the rollers 2 and 3 are side boards 35, extending upwardfrom frame 1. Secured to the front of frame 1 are the noses 20 and 21.At the rear of frame 1 on the rear of arch 41 are lugs 38, in which aresecured the poles 23 and 24. On the right-hand plan view;

side of the machine, immediately forward of arch 41, is the elevator 4.On the drivingaxle are secured two sprockets 16 and 34, side by side. Ashaft 42 is journaled on arch 41 at its upper part transversely to therear ends of rollers 2 and 3. This shaft is geared to wheel 16 on thedriving-shaft by means of the sprocket-chain 17.

7 and 8 are shafts which form rear extensions of rollers 2 and 3,respectively.

12 and 22 are spur-gears on the rear ends of shafts 7 and 8.

10 is a bevel-gear on shaft 42, which meshes with bevel-gear 11 on shaft8.

is a small sprocket-wheel on shaft 42, which receives motion from thedrivingsprocket 16.

13 is a bevel-gear mounted on the righthand end of shaft 42, and 14 is abevel-gear meshing with 13.

31 and 32 are sprocket-wheels connected by sprocket-chain 30, by meansof which the elevator is driven.

29 represents the elevator buckets or cleats.

18 represents a sprocket secured to the outside of the right-hand sideboard 35, the shaft ,of'which passes through said side board andtransmits motion to a sprocket on the inside of the side board, and thissprocket in turn drives the chain 33, which carries conveyerblades 9.

36 is a cross-piece extending from one of the-side boards to the otherand serves for a fastening for spring 37. Spring 37 is made, preferably,of spring-steel and extends backward over rollers 2 and 3. The poles 23and 24 are secured to the rear part of frame 1 in lugs 38. At the rearend of poles-23 and 24 is secured an arched draft-frame 25. From thisframe, which is preferably made of metal, extend the arms 39, to whichare secured swingletrees 40 for attaching the horses.

26 is the steering-wheel, and 27 is the hand-- wheel, disposedimmediately in front of the seat 28, by which steering-wheel 26 isturned.

It will now be understood that as the machine is pushed along over therow of corn the drive-wheel 5 imparts motion through its axle to thedrivingsprocket 16 and this through chain 17 to the small sprocket 15,thus rapidly rotating shaft 42. Shaft 42 imparts motion to bevel-gear10, which in turn causes bevel-gear 11 and roller 3, secured to it, torotate, and spur-gear 22, secured on shaft 8, imparts motion to itscompanion gear 12, and thus causes roller 2 to rotate in the oppositedirection, so that the upper surfaces of rollers 2 and 3 run toward eachother. Rollers 2 and 3 are provided on their front ends for somedistance with deep screwthreads. The threads are so disposed as tooscillate and are so formed as to be deeper in front and becomegradually shallower toward the rear and finally run out. The noses 20and 21 are flared from each other at the forward end, so as to directstalks of corn between them. They are also inclined downward, so thattheir points are in proximity to the ground in order to catch down cornand direct it to rollers 2 and 3. It will be understood that thus thestalks of corn are grasped by the threaded portion of thehusking-rollers 2 and 3 and fed backward by the threads and at the sametime forced downward, and the ears are snapped off the stalks by thetime the stalks have reached the point where the threads run out. Thecars are now delivered to the conveyer-blades 9, attached to chain 33,and are slowly conveyed backward by them over the remaining portion ofsaid rollers. During this movement the husks are grasped by theoscillating rollers and jerked off. As the ears proceed backward theypass under pressure-spring 37, which insures contact with the rollers,in order that every bit of husk may be removed. \Vhen the ears havepassed over the entire length of the rollers 2 and 3, they drop into thespace about the shafts 7 and 8 and then into the boot of elevator 4.Here they are received by the buckets or cleats 29 and elevated and maybe caught in a wagon that may be driven alongside of the machine forthat purpose. The elevator 42 is driven by bevel-gear 13 on shaft 42,which in turn drives bevel-gear 14 and sprocket 32, secured thereto. Weprefer to arrange the machine as shown, so that the horses push it infront of them instead of pulling in the usual way. Thus the horses arehitched to the swingletrees 4:0 and may be haltered to the machine infront of them, and instead of driving or guiding by means of lines theoperator, seated upon the seat 28, steers the machine by means of wheel27.

We are aware that corn-husking machines with husking-rollers have beenmade, and we do not claim the rollers broadly; but,

Vhat we claim as our invention, and desire to secure by Letters Patent,is

1. In a corn-husking machine, the combination of a yoke shaped frame,round and smooth, parallel and approximately horizontal husking-rollersscrew-threaded on their forward ends in such a manner that while thethreads oscillate throughout their length, the troughs of the threadsbecome shallower from the forward end of the rollers backward until theyrun out, leaving the rear and greater portion of the rollers withoutthreads, a driving-wheel, and means for transmitting motion from saiddriving-wheel to said huskingrollers, substantially as specified.

2. In a corn-husking machine, the combination of a yoke-shaped frame,oscillating and approximately horizontally-disposed huskingrollers,rotatably mounted in said yoke-sh aped frame, said husking-rollersscrew-threaded on their forward ends so that the threads oscillatethroughout their length but run out backward, conveyer-blades mounted onatraveling chain so disposed as to travel longitudinally over saidhusking-rollera and a pressurespring disposed longitudinally over saidhusk ing-rollers, substantially as and for the purpose specified.

3. In a corn-husking machine, the combination .of a yoke-shaped frame, apair of oscillating husking-rollers provided with right and left feedingscrew-threads journaled in said yoke-shaped frame, means for impartingrotary motion to said husking-rollers from a drive-wheel, apressure-spring secured longitudinally over said husking-rollers forpressing the ears of corn firmly into contact with said husking-rollers,conveyer-blades extending transversely across said husking-rollers andso mounted on a traveling chain as to travel longitudinally over saidhusking-rollers and under said pressure-spring, poles attached to therear of said frame, an elevator mounted on the rear end of said frame,means for driving said elevator from the drivingshaft of the machine, asteering-wheel at the rear end of said poles, and a hand-wheel foroperating said steering-wheel, substantially as and for the purposespecified.
